Whenever I buy any colloidal silver, I really like this company too, Utopia Silver. They have this silver gel with aloe vera. It should be good. There other products are. I just don't know what PPM is used in it. They are normally very good at responding to contact though.

Cracked heels can be caused from fungus, so maybe peeling skin on your feet is caused from fungus, too. The thing about fungus is it can become immune to an antifungal with repeated use. So, when I mix up a salve to put on my son's boils, which he gets occasionally, I change the mix. I used to put everything I had on hand that I knew to be antifungal including baking soda. Fungus cannot live in an alkaline environment, so that's why baking soda is good. Now, I'm hoping by using a couple of different antifungals each time I use the salve, it will prevent the fungus from becoming immune and the boils will go away permanently.

I don't really know what the difference is exactly, I just know they work!!! Iodine, olive leaf extract, cayenne pepper, turmeric, ginger, orange oil and garlic are also antifungal.
